MOTION -PIGTUBE APPARATUS.

To all whom it may concern:

Be it known that we, RICHARD H. PIETZVSCH, and ROBERT P. Nrorrors, citizens of the United States, of the city and county of Philadelphia, State of Pennsylvania, have invented new and useful Improvements in Motion-Picture Apparatus, of which the following is a specification. Our invention relates to kinetographic projecting or exposure making apparatus wherein is used a film or other picture unit support in which the picture units in the kinetographic series are disposed in longitudinally neighboring rows extending transstantially noiseless and smooth in operation.

versely of the film.

It is the object of our invention to decrease the weight and-therefore the inertia of the moving parts, and particularly the transversely moving parts, which control or operate the film. .As contributing to this end we provide film storage and film rewinding spools or reels which are stationary in the sense that they do not move with the parts which more the film transversely. And in this relation we arrange the film in a flexible loop in advance of and after its engagement by the operating or controllingmeans, whereby the transverse movements of the film are accompanied bylateral fiexures of the film loops.

It is a further object of our invention to improve the mechanism-for controllin the lateral and transverse feeding of the to the end that such mechanism shall be'sub- Our invention resides in these and further features of arrangement 'and combination hereinafter described and claimed.

Referring to the drawings, B is a suitable camera or projector box having the front wall a and the rear wall b.

Within the box B is the plate or wall 0 held in fixed position with respect to the ribs or projections d I proofing material 6 intervening between the projections d and the plate 0.

lower wall 9 resting against or secured to the bottom of the box B. Between the plates (1 and 0 is disposed the rotary shutter it having the are shaped openings indicated at 7', Fig. 1, which during rotation of the shutter allows for a predetermined suitable time free light passage, the openings 7' rotating before the lens k.

With its axis in the optical aXis'of the lens is and of the instrument is a chamber at carried by the plate 0 and terminating at its. inner end in the smaller tubular pro ection 1. The shutter 71. 1s driven by the bevon the box B,ilight eled gear 0' journaled in the plate 0 and meshing with the driving beveled gear 12 secured upon the shaft 9 to which is secured the pinion 1- meshin by the hand crank ttfirough the shaft u. The gear 8. drives also the pinion a secured upon with the gear 8 driven shaft 11; upon which aresecured the variable pitch screws :0. pitched screw threads of which the channels the greater portion of lhe screws it have variably a circumference no pitch longitudinally," V

neighboring channels 3 being connected hy channel y;

the inclined or curved channel portions 2 which are the, only portions having a longitudinal pitch. 'At one end of each of the variably pitched channels y it decreases in depth as indicated by the bottom surface a which rises substantially to the top of the The beginning of the rise a is substantially atthe maximum of the lateral deflect on b which is flanked by the members 0 and al of greater radial depththan the -Disposed parallel with the shaft '-w is the longitudinally movable and rotatable shaft 71. which passes through the wall 2' of the casing. Secured upon shaft k is the pin wheel 7' carrying at'it's one end a circuinferential series of equally spaced pins 70 and at its other enda similar series m the pins of one series at one end being staggered or I alternated in angular position with the pins at the other end, whereby a pin is and a pin m -will not be simultaneously in mesh with their"respective screw slots y, y and thereby become locked.

Carried on the-inside of the casing f is an are shaped plate 01 havingtherein the parallel slots 0 'and'p joined by the curved slot 9 and having the terminal outlets r and. 8. Fig. 11. With these slots cooperate the pins m as hereinafter described.

Secured to the' shaft h to move longitudinally and rotatably therewith is the, film feedingwheel 25 having the teeth a for engagin a single row of perforations in a film, t e wheel :5 being shown'in edge view able transversely upon the stationary bar'or in Fig. 9 on larger scale. The shaft 71, is hollowiand slides longitudinally upon and rotates. upon the bar 1: supported at its outer end in the bracket 111 The film guiding or supporting frame or plate m is'movshaft g and is prevented from rotating thereon. by the lug-'2 which travels longitudinally in a slotin'the longitudinally extending memberja .carried .by the wall a. Theframe m is carried backwardly and forwardly transversely by -the;shaft h by"- being confined between the collar 5?, Fig. 1, j

and the extended hub c 'of the sprocket As seen Fig s36 and the frames has incense pivoted thereto onthe screws (2 the eccentrics or cams e which are drawn toward each other by the spring 7. The lower edges of these cams e engage plates g disposed in openings in the circular bearings k of the member m upon the shafty. The

' bearing 72. is cut away as indicated at 41 Fig-7, so that there are formed points or edges j u The tension of the spring f urges the cams e in such direction as to press the members g against the pin or shaft 1 thus raising the frame :0 and its bearing 71 against the under side of the shaft 1 so that the sides of the bearingsv around to the points 9' engage the shaft 3 giving a 3-point bearing. This structure steadies the movement of the member m and prevents any play between the shaft y and its bearing.

Betweenthe bearing'portions ha of the frame 00 are swung the arms is? pivoted upon the shaft 3 and having pivoted in their outer ends the pressure roller m for pressing the film against the feed sprocket t In the frame al is formedthetransversely extending slot n into which the tubular :projection 47. on chamber 7%,sXtends, as best seen in Fig. 5.- The slot n extends only par tially through the plate'wt. Within the slot 'n rhowiever, are the rectangular openings 0? extending through member a? and be-j tween which are the ribs 29 These rectangular openings 0 are substantially the shape and size of the picture units upon the film,

and there are as many of theseopenings o as there are picture units in a row on the film, the ribs 0 registering with-the spaces between picture units.

LlPivoted on'the vertical pivot screws or' pm 9 carried by the lugs or ears r on the frame w? is the yoke member s carrying at its, outer ends the vertical pivots t upon -which is "pivoted thepressure plate o having rectangular apertures o with intervening ribs 10? registering respectively with the apertures o and ribs 39? in the plate m A plunger m Figs. 1, 4:, 5fand 12, is carried by the frame a: and is pressed outwardly by the spring y Fig. 12, against the extension 2 of the yoke s t-o the rear of-the pivot g; This thrust by the plunger m holds the pressure platefo toward the frame 00 the pressure plate v pressing its ribs p against the .film. As-will be noted from Fig. '12, if the yoke s and'the pressure plate 4;? be swung about the pivot g in a counterclockwise direction, aw ay from theframe a2 ,'the corner or projection a will'ride under and past the plungerm? until the lunger'm engages the 1 surface bywhereby t e plate-o and yoke s will be held by spring pressure away from the plate. m to a ow threading of the film throughthe machine. On the shaft'or arbor se /supported inthe lugs orfears d on the frame w is rotatable the film engaging magma sprocket wheel 6 similar to the wheel I? previously described. On the bracket f carried by the frame m are pivoted the arms g carrying at their outer ends the pressure roller h On the wall a or any other suitable stationary part are disposed the film reel inclosing boxes 7' each having a cover k to completely inclose the film in light proof fashion when required. Near the upper box 9' extends a shaft m driven by gear 01, which is in turn driven by the-gear o driven by the gear 79 which is in turn driven by the pinion a on shaft a which is directly driven by the hand crank t. Secured upon the shaft m is a film engaging and feeding sprocket 9 similar to the. previously described sprocket 25 And cooperating with the sprocket g is the pressure roller 1' carried in the outer end of arms .9 pivoted at 19.

On the shaft 0 driven by the gear p is secured the film take-up sprocket w Fig. 4, with which cooperates the pressure roller .12 carried by the arms 3 pivoted at 2?.- Extending into the lower reel box j is the shaft a upon which is loosely journaled the gear N, Fig. 3, meshing with and driven by the gear p On the shaft a is a collar or washer 0 pressed against the face of the gear 6 by the spring (Z whereby the shaft of is frictionally driven. When the cover 2'0 of the lower film box j is removed a film re-winding or receiving reel 6' having the hub f is slipped into the box 7' as far as the head 9 the hub i being centered upon the shaft a. The reel 6 has secured thereto a flange if having slots y' adapted to receive the pin is driven by the shaft a whereby the reel 6 is driven by the shaft a to rewind the film. i

In Fig. 8 is illustrated the film F having thereon successive transversely extending rows of picture unitsnumbered from 101 to 132 to indicate, by way of example, their order of succession in a kinetographic series.

While the film is here shown as having four picture unitsper row it will be understood that our invention is not limited to this number, since a lesser number or\ a greater number per row maybe employed. Between the lateral edges of the film Fare disposed in a longitudinal row the perfo rations m in which engage the teeth or projections a on the sprocket wheels t, 6 g and 'w 7 By thus using a single row of perforations and placing it'at or near the middle of the film, the effects of lateral shrinkage of they film, due to development and drying, or anyi other causes, are minimized, with the result that the picture units register with greater accuracy with the apertures 0 and the optical system of the apparatus than in the case of a fihn having a double row of perforations as is customary.

While in Fig. 8 we have shown the row of perforations m at the middle of the film, the same may be to one side of the middle, in which case such location of the perforations will insure the film being threaded through the apparatus with the proper side thereof toward the-lens.

As shown the perforations m are disposed at the intersections of the longitudinal and transverse divisions or joints 0 and r between picture units, whereby these perforations do not disfigure or interferewith the picture unit itself. i

Fig. 8 shows these perforations m occurring only once for two rows of picture units, though it will be understood that there may be a perforation m for each row or for other multiple of rows.

It will be noted also that the sides of the perforations m here shown quadrilateral in form, are inclined with respect to the lon gitudinal axis of the film and that the teeth a on the sprocket Wheels are similarly shaped. The result is that as a tooth ti enters a perforation m there. is a wedging action which compels the film F to take such position transversely as to register exactly with the sides and angular edges of the teeth 24 This action upon the film F in-.

sures that it will run perfectly in a straight line between the pressure plate '0 and the plate m with the result that the fihn will have no play or motion laterally, but will" always bring the picture units into exact,

re ister with the optical axis.

' Vhile we have shown the teeth a and apertures m as quadrilateral in form, it will .be understood that they may take other forms, for example, hexagonal; and the sides of the teeth and of the apertures need not be straight, but may be curved. Thus, for example, the apertures and teeth may be elliptical or oval in shape, or of an suitable shape whereby there will be t e lateral wedgin action between the teeth and the edges of the perforations to cause the film to track in a straight line or with accuracy. It will be understood further that the teeth on the'feed sprocket need not have a form similar to or identical' with the form of the perforations, so long as the wedging action takes place. For example, with perforations' having converging inclined or curved sides there may be used on the feed sprocket circularor similar pins which in engaging the convergmg curved or inclined sides of-the perforations will also perform the wedging action- While we prefer to use asingle ,row of perforations in the film for effecting its feeding, it will be understood that in addition to such a single row of perforations we may employ in either or both lateral margins of thefilm or elsewhere one or more rows of perforations, for example of the ordinary type, with-which may cooperate feed and take-up sprockets which may be used in lieu of the sprockets g and w, or either of them. By such arrangement there will be less wear and tear upon the edges of the perforations in the single row, which may then be used solely or substantially solely for accurately determining lateral position or centering of the film,

As 'the film F passes over the sprocket Wheels referred to, the coiperating rollers press the same into proper engagement with the sprocket wheels. These sprocket wheels and pressure rollers have the laterally disposed circular ribs n which register with the marginal spaces 0*, Fig. 8, between pictime units of the film F, these spaces 0*v registering with the ribs 12 on the plate m and on the pressure plate 4: The pressure rollers are all spring pressed against their cooperating sprockets, as by torsion springs,

one of which is indicated at 10 Fig. 1.

The operation is as follows:

The pinion u and gear 8 are rotated at suitsubstant-ially uniform speed by an coordable means, as the hand crank t.

ingly the gear a is driven atuniform speed,

thence into a loose fold or loop Land thencev between the pressure roller 72. and the sprocket "e thence from the right hand side of the sprocket wheel 6 as viewed in Figs.

4 and 5, downwardly between the ribs p on the members 01: and c2, thence over the main intermittent feed sprocket-t between the latter and the roller m thenceinto a loose fold or loop L thenceoverthe takeup sproc et =10 between ,the same and the pressure roller m and thence into the lower box 7' on to the reel 0 on which the film is -wound up, the shaft a being frictionall driven, so that there may beslippage between-the shaft a and its driving gear 6?, whereby as more and more film is wound upon the reel e thelatter will make fewer and fewer revolutions in proportion to the,

number of revolutions of the crank it." 1

It will accordingl be understood that the free folds or loops w, which do not move transversely with the frame 22 The result of this construction is that the sprockets g and 'w and the boxesand L 'in the film'F i are disposed between the sprocl'iets g and v angers j and'their film and reels need not move -with the transverselyv moving frame m whereby the weight and therefore inertia of v the transversely moving parts is greatly decreased, with the result that the apparatus is the more easily operated, and operates more smoothly and w1th far less noise.

The variably pitched screw a: rotates continuously and serves to impart to the frame 00 intermittent transverse movement at the ends of which the feed Sprocket i is rotance equal to the distance between centers of neighboring rows of picture units.

In the position shown in Fig. 1, the frame a is in position for exposure of the end picture unit of arow, as for example, picture unit 108, Fig. 8. hurt errotation of the top of the, member m, lFi 1, toward the observer, will cause the roller pin m to be deflected laterally-toward 72 carrying the pins m to another of the ends 8 of thesl'ot p of member n Simultaneously a pink at the other end of the wheel 3' is opposite the entranc f of the screw thread of the left hand part of the member :0. Further rotation of the member at causes the surface a at the right end of the member a: to rotate the pin m to rotate the wheel 3, thereby entering the pin k into the left hand screw slot and simultaneously withdrawing a pin m from the slot end 8 and entering another pin m into. the slot 1' continued rotation causing the wheel 3" to be shifted slightly towardthe left to a position similar to that indicated in Fig. 1, whereupon the frame. m is in position for exposure of the plcture the partial rotation of wheel j having rotated feed sprocket t} to feed the film F lontated to step the film longitudinally a dis unit 109' at the right end of the next row,

gitudinallyone step. Continued rotation of the member a? then intermittently shifts the wheel j and therefore the frame as. in intermittent steps toward the left by reason of engagement of .a pin 70 in the left hand screw slot 3 Simultaneously the pin which entered the slot r moves toward the left in the slot 0 with these same intermittent movements, thus causing exposure in succession of the picture units 110, 111 and 112.

After unit 112 has been exposed the pin 70 is shifted laterally at 1) at the left end of pin in the slot 0 has passed through the curved slot 9 into the slot 2 by a lateral 'the member ai,-'a'nd then moves ba'ckwardly, again, but during such movements the part a rotates the pin is, and simultaneously thei12oandreturnmovement combined with a rov tary movement at the time a pin m has'entered at 7' into the leftend of the-right hand screw slotg.

In other words, the. pin m enters the member n at the slot 1' passes stepwise to-, I

ward the left through the slot 0 then by a lateral left hand and right hand movement movement passes from slot (1- into slot 17 right in the slot p by step movements,

caused by parts 5 and a at one end of screw member w, and finally out at slot 8 at the time the'second pin enters r Each rotative movement of the wheel 9', at the end of the lateral movements, and during the extra lateral and return movement of the frame :0 rotates the feed sprocket t through an angle suflicient to step the film longitudinally a distance equal to the distance betweencenters of adjacent rows of picture units to bring the next row of picture units into op rative position.

These lateral moveme ts of the frame m are permitted by the 100 L and L and the film continuously pulled out of the upper box 1' by sprocket g and continuously taken up by take-up sprocket 'w and delivered to the rewinding reel in the lower box 3' is intermittently fed as to the part between loops L and L by the sprocket t whichinoves with the frame a. Between the loops L and L the film is engaged by the feed sprocket t and the idler sprocket e the rotation of the latter by pull exerted on the film by sprocket 25 being opposed by friction, whereby the film between the sprockets e and 6 isheld stretched or taut, with the result that theengagement of the film by these sprockets c and t insures its accurate lateral positioning with respect to the optical axis or the means which move the film laterally.

- Between transverse movements of the wheel 5 it is locked against any transverse movement or oscillation by confinement between neighboring locking ribs g on the member 11:; and the longitudinal slots 0 and p in one or the other of which a pin is always confined durin lateral movement of h the frame :0 positive y locks the wheel j against any rotative movement which in one dlrection would tend to pull the film F downwardly between plate a or the pressure plate '0 or in opposite direction would tend to loosen the film.

The rate of the continuous rotation of the shutter b is such that the slots or apertures j rotate in front ofthe lens 7: only while the frame 00 is at rest.

By the apparatus described a continuously rotating cam or variablypitched screw imparts intermittent lateral and rotative movements to the shaft h, which imparts intermittent lateral movements in both directions to the frame as? and intermittent rotative movements always in the same. direction to the feed sprocket t the film storage and rewinding reels are stationary in the sense that they do not move with the frame at, and the sameis true of the sprockets g and 'w only the feed sprocket t and the sprocket e mom with the frame, t pulling downwardly intermittently upon the film F against while a the opposition by the sprocket e occasioned by the friction caused by the thrust .of the end of the sprocket 6 against the lug or ear d caused by thespring g Fig. 6. v

t will be understood that our invention herein claimed is not limited to the use of any particular structure of the film, and that film of the character herein described, having a single row of perforations or otherwise formed, may be used, films of any other forms, such as those having the usual double rows of perforations, may be employed.
